Biased decision-making processes in aggressive boys.

Recent evidence has suggested that aggressive boys demonstrate a bias toward attributing hostility to peers in unwarranted circumstances. This study explored two aspects of cognitive processing that might be related to attributional bias: speed of decision making and selective recall of hostile cues. Groups of aggressive and nonaggressive boys at three age levels participated in a detective game in which the task was to accumulate evidence in order to decide whether or not a peer had acted with benevolence or hostility. Aggressive boys were found to respond more quickly and with less attention to available social cues than nonaggressive boys. Aggressive boys also overattributed hostility to peers in unwarranted circumstances, but only when they responded quickly. This restriction suggested that training aggressive boys to respond more slowly could lead to fewer biased attributions on their part. Selective recall was also related to biased attributions, for both groups of boys. This suggested that training boys to recall all cues nonselectively could reduce the frequency of their biased attributions. The results are discussed in terms of a cognitive model of aggressive behavior. Because of the correlational nature of this study, the conclusions are stated as tentative.
